Half-Dragon Monks/Druids would be a case of "specific trumps general", so I still don't see any contradictions. There is no location discussing Frightful Presence, DR and SR that is discussing all True Dragons and not just the MM10, so we can't use those as evidence (wings are also irrelevant as most Lung dragons and Brown dragons lack them, so they're clearly not a defining characteristic). The fact that all UATDs have these is overall irrelevant because there is no place in the rules that actually says that True Dragons must have these qualities (Kobolds have natural armor, so no issue).
The goal is, apparently, to determine which definition results in the least contradictions. Therefore, we must look at all descriptions, accurate or not, and determine which definition results in the least number of contradictions. Both definitions result in contradictions with things like having wings, claws, an energy immunity, etc. However, JaronK's argument suffers from the fact that DWK's contradict the descriptions that all true dragons have DR/SR/Frightful Presence that manifest and increase with age.
The natural armor part was something I added in from memory, as I think I remember there being a description of True Dragons saying their natural armor increases with age, which DWK would also contradict.
And no, Beholder, I have been reading all of your posts (though skiming over your trolling). You still haven't explained why JaronK is wrong on many points. At absolute best, you have come up with another reading of the same rules that removes DWK's as being True Dragons (albeit using some uncommon definitions of words), but you haven't disproved the reading saying that DWK's are True Dragons.
And he hasn't disproven mine, either, so what's your point?
However, I have shown that my definition results in less contradictions with existing descriptions, which is apparently the actual goalpost of the argument according to JaronK.
Oh, and computer logic will always come to being True trumping Lesser because computers ALWAYS go in order, and True is defined first in the Draconomicon.
I don't see how this is pertinent information.
